I contacted DW/CZ customer service via email for some parts.  Thought the rest fo you DW fans would be interested in the response I received today.  I posted the entire message for context:
Hello Michael.  I'm sorry the grips are not available at this time.  We were recently acquired by CZ-USA.  We are currently not making revolvers.  We  will be starting up production again probly within a few months.  We are out of the target style grips.  The only grips we have in stock are the Hoag fingergrooved grips.  The front sight is $13.00.  The .285 ht., .125 wdth.  Shipping charges are $3.00 regular mail.  We accept Mastercard, Visa, and money orders payable to CZ-USA.  Thank you for contacting Dan Wesson Firearms.

At least there is an assurance of production starting again.  I'd like to get a stainless "twin" for my blued model 15 eventually, and access to parts and service would be a bonus.  I responded, suggesting that once they start production again, they might want to look into the compact revolver business, since CCW is the hot market today.  Probably won't happen, but a guy can dream.  I know I would buy a 5 shot DW .357 with 2,3, and 4 inch barrels, especially if they could get the frame size down to say, an SP101.
